The report read: "The passenger train was the 5.40am South West Trains service from Waterloo to Guildford and comprised 10 coaches, a combination of class 455 and class 456 electric units.

"The wagons were standing on a line adjacent to the intended route of the passenger train and had been provided as a safety barrier separating passenger services from an area where construction work was being undertaken as part of the Waterloo station upgrade project."
